Most implementations I've seen will give a struct the alignment of its
strictest member.  Thus, struct{char} and struct{int} may have different
alignment constraints.  However, I believe the dpANS requires that all struct
pointers must be interchangable anyway, so this does not invalidate your
suggestion.

How would you use such a feature, if you had it?
